Well because there is a total of 55 students that will be your denominator

And there are 22 seventh graders so that would be you numerator since you want to know the percentage of the seventh graders present in the club.

To do so you just need to divide 22 by 55 and multiply that quotient by 100 and slap on that percent sign:

100 * (22 / 55) = 40%

<span>The Briarwood Middle School chess club has 55 members. 22 of the members are in seventh grade.

To convert a fraction into a percent divide the numerator by the denominator and then multiply that result with 100. We can show this formula by <span>(Numerator/Denominator)*100. 

</span>(22/55)*100 

<span>= 40.00%

</span>= 40%

The speed of boat in still water is 15km/hr if needs 4 more his to travel 63 km against the current of a river than it needs to
hram777 [196]

Answer:

\frac{63}{15  - c} - \frac{63}{15  + c} = 4

Step-by-step explanation:

The systems of equations are

Let us assume the rate of the current be c

Now actual speed against the current is (15 - c)

And, the actual speed with the current is (15 + c)

Here we applied the time formula i.e. distance by speed

Also the upstream time  - downstream time = 4

Now the equations are

\frac{63}{15  - c} - \frac{63}{15  + c} = 4

A crew of highway workers paved 1/2 mile in 1/4 hour. If they work at the same rate, how much will they pave in one hour?
mote1985 [20]

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20

minutes. The longer the time, the more they will pave.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by

20

) and them multiply by

60

to find how much in one hour.

The admission fee at a local zoo is $1.50 for children and $5.00 for adults. On a certain day, 3000 people enter the zoo and $9,
vlabodo [156]

1600 children and 1400 adults attended

<h3>How to determine the number of adults?</h3>

Let the children be x and adult be y.

So, we have the following equations:

x + y = 3000

1.5x + 5y = 9400

Make x the subject in x + y = 3000

x = 3000 - y

Substitute x = 3000 - y  in 1.5x + 5y = 9400

1.5(3000 - y) + 5y = 9400

Expand

4500 - 1.5y + 5y = 9400

Evaluate the like terms

3.5y = 4900

Divide both sides by 3.5

y = 1400

Substitute y = 1400 in x = 3000 - y

x = 3000 - 1400

Evaluate

x = 1600

Hence, 1600 children and 1400 adults attended
